Abstract
The present invention provides a polymeric-type antistatic agent containing a polymer composition consisting of a polymeric-type antistatic agent containing a resin or/and an elastomer as a main component thereof; or/and a thermoplastic resin having a polar group or/and an elastomer having the polar group. At least one kind of an anion-containing salt, having a fluoro group and a sulfonyl group, is added to the polymer composition without intermediary of a medium consisting of a low-molecular-weight polyether-containing compound or a low-molecular-weight polar compound whose number-average molecular weight is not more than 5000. The present invention also provides a composition, for a conductive roller or the like, containing polymer components and the polymeric-type antistatic agent dispersed in the polymer components.
